CYLINDER FOR CARDlNG-MACHINES, 84.0.

SPECIFICATION forming part of Letters Patent No. 405,234, dated June 11,1889.

Application filed July 30, 1888. Serial No. 281,396. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE O. IVICKERS, of Lawrence, county of Essex,State of Massachusetts, have invented an Improvement in Cylinders forCarding-lvlachines, &c., of which the following description, inconnection with the accompanying drawings, is a specification, likeletters on the drawings representing like parts.

This invention has for its object to improve the construction ofcylinders used in carding and other machines containing cylinderssupplied with card-clothing.

In accordance with my invention the cylinder is made up of a series ofspiders having flanges, and of a series of substantially hollow metalliclags, the latter being bolted to the spiders.

As herein shown, the lags have pockets, and

the flanges of the spiders have openings or recesses for the receptionof bolts by which to unite the parts, and as shown in this embodiment ofmy invention the metallic lags are alternated with non-metallic stripsor por- 2 5 tions, in which may be driven the tacks or nails employed tosecurethe usual card-clothing to the surface of the cylinder.

My improved cylinder has great strength and durability ascompared withother cardin g-cylind ers heretofore known to me, and the lags beingmade hollow or flanged, as will be described, makes it possible toreduce their weight, so that they are not objectionable in thatdirection. 7

3 5 My improved lags are composed of flanged plates.

My invention consists, essentially, of a shaft, the attached spiders,the metallic lags having beveled sides, and means to connect the lags tothe spiders, combined with wedge-shaped nail-holdin g strips inserted inspaces between the adjacent lags and held between them by the saidbeveled sides of the lags, substantially as will be described. 5 Otherfeatures of my invention will be pointed out in the claims at the end ofthis specification.

Figure 1, in front elevation partially broken out, represents a cylinderembodying my invention. Fig. 2 is an end elevation of the cylinder shownin Fig. 1,partiallybroken out, however, to better show the constructionof parts. Fig. 3 is an under sideview of one of the lags. Figs. 4. and 5are respectively sections of Fig. 3 in the line a: or; and Fig. 6 is aperspective detail of portions of one of the spiders, to better show itsshape. Figs. 7 and 8, on a smaller scale, show a modified form of myinvention to be described.

The shaft a, as herein shown, has fixed to it three spiders I), havingflanges 2, the outer portions of the said flanges having raisedprojections 3, (see Figs. 1 and 6,) which are slot-ted, as at 4. Thelags c are of metal and hollow, so as to constitute a shell havingflanges, as best represented in Figs. 4. and 5, the outer face 6 of eachlag being slightly convex, the outer sides of the flanges 7 beingtapering and at suitable distances apart. The said lags at theirinterior have lugs or projec- 7o tions, as 8, to leave between them andthe outer portions of the lags, pockets, as 10, (see Figs. 4 and 5,) forthe reception of the heads 12 of suitable bolts (Z, the bodies of whichenter the slots 4, nuts 13, screwed upon the said bolts below the saidflanges b, causing the bolts to thus securely but detachably fasten themetallic lags to the spiders.

The metallic lags shown in Figs. 1 and 3 are supposed to be made of castmetal; but they may be made from sheet-metal blanks of the shape shownon a smaller scale in Fig. 7, the same being bent into the formrepresented in Fig. 8, said lags being opened at the end; but, ifdesired, the sheet-metal blanks may have projections 15, as representedby dotted lines, Fig. 7, to constitute end pieces for the lags.

Between the metal lags and alternating with them I have secured to thecylinder nailholding strips, as (1, into which may be driven nailsusually employed to confine the usual card-clothing to the periphery ofthe cylinder.

In practice these nail-holdin g strips d will be composed of Wood, and,asherein shown, the strips are of wedge shape in cross-section to fitthe Wedge-shaped or inclined or beveled sidesof the metallic lags, thelatter acting to hold the strips d in position. WVhen the metallic lagsare applied to the spiders, the open under sides of the lags it theprojections 13 of the spiders, the said projections preventing the lagstwisting out of place.

I claim 5 1. The shaft and its attached flanged spiders, havingprojections 3 and openings 4", combined with the hollow metallic lagsshaped to embrace the said projections, and having pockets, and withbolts to confine the said to lags to the said flanp'es, substantially asdescribed.

The spiders, the metallic lags having tapered or beveled sides, andmeans to connect the lags t0 the spiders, combined with wedge-shapednail-holding strips inserted in I5 spaces between the sides of theadjacent lags, and held therein by the said beveled sides of the lags,substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two sub- 20 scribing witnesses.

GEORGE O. WICKERS.
